SPECIFICATION formingjpart of Letters Patent No. 437,559, datedSeptember 30, 1890.

Application filed March 21, 1890i To all whom it may concern.-

Be it known that I, FREDERICK FRANKLIN BLANDIN, a citizen of the UnitedStates, residing at Racine, in the county of Racine and State ofWisconsin, have invented certain new and useful Improvements in Latches;and I do hereby declare the following to be a full, clear, and exactdescription of the invention` such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in latches; and it consists incertain novel featuresas will be hereinafter described and claimed.

The object of my invention is to provide a latch which will be verysimple in its construction and which can be easily attached to a door,and by means of which the door will be securely held and prevented fromswinging in either direction without necessitating the springing of thelock-bolt.

In the accompanying drawings, which fully illustrate my invention,Figure l is a perspective view of the latch in its operative position.Fig. 2 is a vertical section of `the same,

showing a part of the door-frame, and Fig. 3

is a horizontal section, showing a portion of the door inclosed withinthe fastener.

The same letters of reference indicate corresponding parts in all thefigures.

Referring to the several parts by letter, A indicates a plate, whichmaybe of any desired size and of any suitable material, which isprovided at its upper end with a series of teeth or securing-points B,extending in at right angles to the plate-body, while at its lower endthe plate is provided on its inner side with a block or lug C ,of aproper size to adapt it to fit in the bolt-hole of the keeper employedwith the ordinary lock.

To the inner side of the plate A is riveted or otherwise secured thestationary hingeleaf D, to the projecting ends of which are pivoted orhinged the swinging leaves or locking-arms E.

To secure my improved lock or fastener in operative position it isplaced against a doorframe, as clearly shown in Figs. 2 and 3, with thelug C at its lower end fitting in theY keeper 'serial no. 344,732.(Model.)

right angles to the plate A. The door H is then closed, when, if it is aswinging door, it will be stopped by the outer leaf E, and the linnerleaf Eis then turned against the inner side of the door, as most clearlyshown in the sectional view, Fig. 3.

The leaves E are hinged to the ends of the plate A so that they willwork stiftly on their hin ges, and when they are thus turned out atright angles to the plate A to hold the free edge of the door betweenthem, it will be seen that the door will be stopped and held in itsclosed position without having to spring its bolt-lock.

The plate A may be formed with only the teeth B at its upper end, orwith only the lug C at its lower end, to hold it in position.

It is obvious that the stop-leaves E can be hinged or pivoted directlyto the edges of the base-plate A without departing from the spirit of myinvention.

It will be seen that my new and improved latch or fastening device isvery simple and cheap in construction, that it can be readily applied,and that it will eectually hold the doorand prevent its beingaccidentally opened or from swinging to either side.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a doorsecurer, the plate adapted to be secured to a door-frame andhaving hinged to both of its edges the adjustable leaves E E, adapted tobe folded toward each other and against the opposite sides of the doorand to permit the opening of the door in both directions, substantiallyas set forth.

2. A latch consisting essentially of a baseplate adapted to be securedvertically to the door-frame and provided at its lower end with a lugadapted to engage the bolt-hole of the keeper in the door-frame and apair of lockingarms carried by the said base-plate and adapted to swingtoward each other and against the opposite sides of the door, as setforth.

3. The combination of the plate A, having 5 the lug C at its lower endand the series of teeth or projections at its upper end, and the pair oflooking-leaves carried by the baseplate and adapted to swing toward eachother and against the opposite sides of the door, substantially as setforth.

In testimony Whereof'I affix my signature in presence of two Witnesses.
